The Emergence and Molecular Characteristics of New Delhi Metallo β-Lactamase-Producing Escherichia coli From Ducks in Guangdong, China.

ABSTRACT: This study aimed to determine the prevalence and transmission characteristics of New Delhi metallo β-lactamase (NDM)-producing Escherichia coli from ducks in Guangdong, China. In this study, a total of 28 NDM-producing E. coli isolates were recovered from 88 unduplicated diseased duck samples (31.8%) from veterinary clinics in Guangzhou, Foshan, Qingyuan, and Huizhou. Two variants, bla _NDM-1 and bla _NDM-5, were detected and the latter was present in 89.6% of the isolates (25/28). Multilocus sequence typing (MLST) analysis indicated that these E. coli isolates possessed six distinct STs, and ST156 was the most prevalent followed by ST648, ST746, ST354, ST10, and ST162. In addition, phylogenomic analysis found that two of the isolates
